O-arm combines features of a traditional C-arm with an intraoperative 3D scanner for image guidance during surgical procedures. The system allows for lateral patient access, and provides 3D and 2D fluoroscopic imaging; it can also be interfaced with Medtronic Navigation's image-guided surgical software.
O-arm uses a flat-panel digital detector that allows a 360° scan. Datasets consist of 192 slices at 0.4-mm slice widths, and are compatible with the DICOM 3.0 format. The system has been shipping since April 2006.
